1 Claim.

My invention pertains to wash wringers, and has for one of its objectsto provide a simple and effective strippervroll, preferably in the formof a brush, and associated with the upper squeeze roll of a wringer,whereby the material fed through the machine is stripped from thesurface of the upper roll.

Another object of my invention is to provide a pair of brushes suitablygeared to the wringer rolls, whereby the material fed throu-gh the saidwringer rolls is stripped from the surface of the upper roll,irrespective of the direction the material may be fed through thewringer rolls.

Another object of my invention is to provide cylindrical stripperbrushes of cheap construction formed from coiled wire strands, andhaving bristles coiled therebetween, these brushesbeing capable of readyinsertion into journal sockets associated with the Wringer, and when sodesired they are in gear connection with the wringer roll.

With the above and other minor objects in view, the invention consistsin certain peculiarities of construction, as fully set forth hereinafterwith reference to the accompanying drawing and subsequently claimed.

In the drawing:-

Figure 1 represents a sectional elevation of a wash-wringer, havingattached thereto a pair of stripper brushes embodying the features of myinvention.

Figure 2 is a side elevation of the same, with parts broken away and insection to more clearly illustrate structural features particularlypertaining to the drive mechanism for the brushes.

'Figure 3 is an end view of the wringer with parts broken away and insection to more clearly illustrate the structural features,said end viewshowing one method of gearing whereby the brushes are positively drivenfrom the lower roll.

Referring by characters to the drawing, I represents any standardwringer frame provided with upper and lower wringer rolls 2--2,respectively, these rolls being in positive gear connection, asindicated at 3, it being understood that these gears are provided withthe usual housing. The shaft 4 of the lower roll extends into the usualgear housing 5, supported by a column 6, which carries a motor-drivenshaft for'imparting power to the shaft 4 through nested gears containedin the housing 5 (not shown). The housing 5 is provided with anadditional housing 5', which is secured to the wringer frame, and whichencases a gear train for driving stripper brushes 1 1.

In this exemplification of my invention the gear train comprises aproportionately large gear 8, which is fastened to the roller shaft 4,land meshes with smaller toothed gears 9-9', which toothed gears arecarried by stud shafts I0 journalled in bearings formed in the housing6. These stud shafts carry keyed sockets II for'the reception of the endtrunnions I2 of the brushes. These end trunnions carry pins I2 adaptedto enter the keyed slots of the sockets II, whereby a quick coupling iseffected when the brush is inserted in its bearings.

The opposite end journal I3 of the brush is fitted in a bearing I4carried by the wringer frame, and this bearing has mounted therein aspring I5 and follower, whereby the end journal can be adjusted in itsbearing, and the opposite end of the brush is then locked into thecoupling II.

From the foregoing description it will be observed that the cylindricalstripper brushes can readily be adjusted to the wringer, and when soadjusted they are positively driven through the train of gearspreviously described.

As best shown in Figure 1 of the drawing, the wringer rolls are rotatedto feed material from right to left in the direction indicated by thedotted arrows A. As the material is fed through the wringers, the iirstbrush'l, due to its direction of rotation, will tend to aid in feedingthe material between the wringer rolls, and should said material, as itis discharged from the wringer, adhere to the outer face of the upperroll, obviously the cylinder brush 1', travelling in the direction asindicated by the arrow, will strip said material from the upper roll,and cause it to feed smoothly to the discharge point.

Obviously, if the Wringer is reversed, the feed of the material wouldrun through the wringer rolls from right to left, in which case thebrush 'I' would aid in feeding the material between the wringer rolls,and the brush'l would then serve to strip the material from the surfaceof the upper roll. It is understood that the brushes 'I and l arepreferably driven at higher peripheral speed than the speed of the upperwringer roll.

While I have shown and described my invention minutely as to details, itis obvious that I may vary said details as come within the scope of theclaim:-

In a wash wringer, the combination with the upper and lower wringerrolls thereof having an operative connection at one end, of a stripperdevice for the upper roll including rotatable stripper brushes engagingthe opposite sides of the upper roll, a relatively large gear rotatablewith the lower roll and having a greater diameter than the upper andlower rolls, and pinions rotatable with the stripping brushes meshingwith the opposite sides of the relatively large gear above the lowerroll.
